The GOP lawmaker wrote that the NCAA has not done enough to protect women’s athletes despite boasting about collegiate stars at the Paris Olympics. Blackburn pointed to scientific studies that showed "males have inherent athletic advantages over females due to their anatomy and biology."

"While men may have inherent athletic advantages, they have no advantage over women in their level of passion, drive, or desire to compete," Blackburn’s letter reads. "The very bedrock of sport is the exhibition of a commitment to excellence, grace under pressure, and fair play among competitors — all of which is threatened absent an even playing field.

"Women deserve that even playing field and chance to compete, one that can only be achieved by ensuring that only females compete in women’s sports. We urge you to follow the lead of the NAIA and the Court of Arbitration for Sport and adopt policies that protect women’s sports."
